What are the common diseases?

Common diseases are Fusarium wilt, powdery mildew, leaf spot, gray mold, rust and mosaic. The best way to prevent diseases is "prevention is more important than cure".

① From the source, many pathogens come from soil. In the process of raising seedlings and buying seedlings, the soil or materials used need to be disinfected at high temperature, which is very effective for disease prevention.

② The water in close contact with flowers should be kept clean and sterile. Otherwise, the water with bacteria will infect the flowers by spraying water and watering. Flowers are wet in the open air by rain and wet fog with bacteria, and various disease spots will appear after infection.

(3) Prevent the bites of aphids, thrips and other harmful insects, which are also the vectors of viruses.

Targeted fungicides should be sprayed regularly. If the disease has just occurred, spraying drugs immediately can prevent the spread of germs and reduce losses. Spraying 50% carbendazim wettable powder 800 times for Fusarium wilt; Spraying 20% triadimefon EC 1500 times solution on powdery mildew; Leaf spot was sprayed with 800 times solution of 75% chlorothalonil wettable powder; Gray mold was sprayed with 50% procymidone wettable powder 1500 times; Spraying 800 times 80% mancozeb wettable powder on rust; Mosaic disease was sprayed with 400 times of 20% Virin.
